IPC: B32B15/08
Filed: 1991-02-20
Abstract: PURPOSE:To obtain a laminated plate for electricity with an improved twisting characteristic by adding oligomer with a reactive group to a thermosetting unsaturated resin and then reducing a linear expansion coefficient of the laminated plate. CONSTITUTION:A substance which is liquid at room temperature and does not generate a volatile by-product at the time of curing is used as a thermosetting unsaturated resin. In this kind of substance, a resin before curing includes a double connection unsaturated group which can be polymerized radically and is cured by radical polymerization of an unsaturated group. For example, examples include unsaturated polyester, epoxyacryl, and urethaneacryl An oligomer with a reactive group is added to a thermosetting unsaturated resin. In this case, the oligomer reacts with the unsaturated resin through a functional group and needs to be separated after curing reaction. A polyethyrene propylene oxide copolymer with a double coupling at the end is desirable as this kind of oligomer.

Filed: 1979-04-20
Abstract: PURPOSE: To obtain a negative type display device requiring an electric field applying means only at the display pattern section by using a light scattering accumulation state resulting from thermo-optical effect at the background of display.  
     CONSTITUTION: Transparent electrode 2 and oriented film 5 are formed on glass substrate 1. Nematic-cholesteric mixed liq. crystals 4a, 4b are held between a pair of substrates 1, heated once to the transition temp. to the liq. phase or above, and cooled to ordinary temp. to obtain the title device. Crystals 4a, 4b are the same liq. crystal, yet the portion between electrodes 2, 2 is regarded as crystal 4b, and the other portion as crystal 4a. The portion of crystal 4a is maintained at a light scattering accumulation state, and by applying a voltage crystal 4b of the voltage-applied portion becomes of a focal conical light scattering state. By suitably selecting the oriented film and the liq. crystal composition, however, the above-mentioned light scattering states can be made alike to each other, and negative type display can be accomplished at a transparent state using the light scattering state as the background.
